Best Practices Guide for Zebra Wi-Fi 6E Deployment

Quick Guide for 6GHz Deployment

This guide provides best practices for deploying 6GHz Wi-Fi 6E networks using Zebra mobile computers (TC53, TC58, TC73, TC78) and Cisco WLAN infrastructure. The 6GHz band offers increased capacity, higher data rates, and lower latency, making it ideal for enterprise environments like retail, healthcare, and manufacturing.

Device Settings

Proper device configuration is essential for optimal 6GHz performance. Zebra devices support various channel masks and band preferences.

• ChannelMask_6.0GHz: Configure based on country-specific allowed Preferred Scanning Channels (PSC).
• Band Selection: Recommended settings include Auto/all channels, or specific combinations like 2.4GHz and 6GHz, or 5GHz and 6GHz.
• Band Preference: By default, devices prefer 6GHz or 5GHz.
• Power Save: TWT (Target Wake Time) is enabled by default to optimize battery life in dense environments.
• 802.11k/v/w: Keep these features enabled to improve roaming and network discovery.

Common Infrastructure Recommendations

To ensure reliable connectivity, configure your infrastructure with the following parameters:

• Channel Width: 80MHz is recommended for better throughput and application performance.
• Target Wake Time (TWT): Enable to minimize contention.
• Multiple BSSID: Enable to reduce RF interference and overhead.
• Data Rates: For voice deployments, use 12 Mbps as the minimum bitrate.

Security Recommendations

6GHz networks enforce robust security standards. Open security and WPA2 are not supported.

• WPA3 Enterprise: Uses PMF (Protected Management Frames) and supports 192-bit mode with EAP-TLS.
• WPA3 Personal: Uses SAE (Simultaneous Authentication of Equals) with PMF required.
• Enhanced Open: Based on OWE (Opportunistic Wireless Encryption) for data privacy in open networks.

Channel and Regulatory Information

The 6GHz band covers 1200MHz (5.925GHz to 7.125GHz). Deploying Access Points on PSC channels significantly improves network discovery time for client devices.

• PSC Channels: There are 15 designated PSC channels. Scanning these first optimizes connection time.
• Standard Power (SP): Requires AFC (Automated Frequency Coordination) system access. Client devices must set transmit power 6 dB below the AP.
• Low Power Indoor (LPI): Designed for indoor use with specific power limits.

Performance and Optimization

Utilizing 80MHz channel width provides significantly higher throughput and lower latency compared to 20MHz. MU-MIMO (Multiuser MIMO) is highly effective for high-throughput applications, with performance gains most noticeable when the number of participating devices is within the AP's MIMO capabilities.
